| 제목 | Phase Equilibrium Calculations of CO2-IL System Using Cubic EoS and GC NLF-HB EoS |
| 초록 | Having negligible vapor pressures and the ability to dissolve both organic and inorganic substances, room temperature ionic liquid(RTIL)s are actively studied as a leading candidate to replace many of the organic solvents used in present industries. Because almost endless combinations of cations and anions are possible, a model which can predict the behavior of an IL from its structure is appreciated. In this work, the phase equilibrium behavior of a number of carbon dioxide +IL systems is examined. The solubility data of carbon dioxide in differentILs are correlated using two equations of state Peng-Robinson, and group contribution hydrogen bonding non-random lattice fluid (GC NLF-HB) EoS. The calculated results are compared to evaluate the ability of the NLF-HB EoS as a model to describe the phase equilibrium of CO2+IL systems. |
